Safety Instructions

General safety instructions

For qualified staff only

This manual is intended exclusively for acknowledged and qualified electricians who are totally
conversant with the safety standards of electrical drive and automation technology. Project
management, installation, setup, maintenance and testing of the equipment must be carried out
by an acknowledged and qualified electrician who is totally conversant with the safety standards
of electrical drive and automation technology.

Proper use of equipment

MELSERVO-Series equipment is only designed for use in the areas described in this manual.
Be sure to comply with all the characteristics stated in this manual. Only additional or
supplementary devices recommended by MITSUBISHI ELECTRIC EUROPE may be used.

Any other use or application of the products is deemed to be improper.

Compliance with EC Directives

EC directives are intended to allow the liberal sales of goods within the EU. With the
establishment of “essential safety regulations” the EC directives ensure that technical barriers
to trade between member states of the EU are excluded. In the member states of the EU the
machine directive (in force since January 1995), the EMC directive (in force since January 1996)
and the low-voltage directive (in force since January 1997) of the EC directives determine the
guarantee of the presence of fundamental safety requirements and the display of the “CE” mark.

Conformity with EC directives is indicated by the submission of a Declaration of Conformity as
well as the display of the “CE” mark on the product, its packaging or its operating instructions.

The above directives relate only to devices and systems and not to single components, unless
the components have a direct function for the end user. As a servo amplifier together with a
servo motor have to be installed with a controller and other mechanical parts in order to serve
a useful purpose for the end user, servo amplifiers do not possess this function. Consequently
they can be described as a complex component for which a conformity declaration or the “CE”
mark is not required. This position is also supported by CEMEP, the European association of
manufacturers of electronic drive technology and electrical machines.

The servo amplifiers do, however, comply with the relevant low-voltage directive, which is a
prerequisite for the “CE” mark on machines or accessories in which the servo amplifier is used.
To ensure conformity with the requirements of the EMC directive, MITSUBISHI ELECTRIC has
produced the manual “EMC INSTALLATION GUIDELINES” (article number: 103944) in which
the installation of the servo amplifier, the construction of a control cabinet and other installation
tasks are described. Please contact the relevant sales partner who is responsible for you.

Special safety instructions

The following notes on sources of danger should be interpreted as general guidelines for servo
drives in association with other devices. These precautions must always be observed in the
design, installation and operation of all control systems.

DANGER:

Observe all safety and accident prevention regulations applicable to your specific

●

application. Installation, wiring and opening of the assemblies, components and
devices may only be performed with all power supplies disconnected.

●

Prior to carrying out any installation work, wiring and opening assemblies,
components and devices you must disconnect the power supply to the units and
wait for at least 10 minutes. Prior to touching anything measure the residual voltage
in condensers, etc. with a voltmeter to ensure that the voltage has been sufficiently
reduced.

●

Never touch the servo amplifier or servo motor or the optional brake resistor during
or shortly after operation whilst they are still live. The components can get very hot
– there is a risk of getting burned.

●

Assemblies, components and devices must always be installed in a shockproof
housing fitted with a proper cover and protective equipment.

●

Devices with a permanent connection to the mains power supply must be integrated
in the building installations with an all-pole disconnection switch and a suitable
fuse.

●

Ground the servo amplifier and servo motor securely.

●

Check power cables and lines connected to the equipment regularly for breaks and
insulation damage. If cable damage is found, immediately disconnect the equipment
and the cables from the power supply and replace the defective cabling.

●

Before using the equipment for the first time check that the power supply rating
matches that of the local mains power.

●

EMERGENCY OFF facilities in accordance with VDE 0113 must remain effective in
all operating modes of the servo motor. The EMERGENCY OFF facility reset function
must be designed so that it cannot cause an uncontrolled or undefined restart.

●

The EMERGENCY OFF facility must be wired so that the electromagnetic brake is
also activated during an EMERGENCY OFF.

●

Residual current protective devices pursuant to DIN VDE Standard 0641 Parts 1–3
are not adequate on their own as protection against indirect contact for installations
with servo amplifier. Additional and/or other protection facilities are essential for
such installations.

Special safety instructions for the devices

CAUTION:

During the installation of servo systems beware of the heat that builds up during

●

operation. Make sure that there is adequate clearance between the individual
modules and enough ventilation to allow the heat to be dissipated.

●

Never install servo amplifiers or servo motors or the optional brake unit close to
easily flammable materials.

●

When using a servo system always observe strict compliance with electrical
characteristics and physical dimensions.

●

In the event of a defect arising in the servo amplifier, servo motor or optional brake
resistor immediately switch the power off to the servo drive, as otherwise it may
lead to overheating and self-ignition of the devices.

Environment

Operate the servo amplifier at or above the contamination level 2 set forth in IEC60664-1. For
this purpose, install the servo amplifier in a control box which is protected against water, oil,
carbon, dust, dirt, etc. (IP54).

Grounding

To prevent an electric shock, always connect the protective earth terminals of the servo amplifier
to the protective earth of the control box. Do not connect two or more ground cables to the same
protective earth terminal.

Features and configuration Introduction

1 Introduction

1.1 Features and configuration

Apart from possessing the functions of the servo amplifiers MR-J2-Series, the servo amplifiers
MR-J2-Super have additional features and functions.

The servo amplifiers MR-J2S-B and MR-J2S-B4 are designed for operation with a Mitsubishi­Motion-Controller via a serial bus (SSCNET). For this the servo amplifier reads in the position
data directly so that it can then execute the positioning process.

Through the specification of speed and direction of rotation via the command unit, precise
positioning is possible. To protect the power transistor against over-current resulting from great
accelerations or delays or overload the servo amplifier is equipped with a speed limitation
feature. The value for speed limitation can be varied and may be specified via an external
analogue input or a parameter.

The RS232C or RS422 interface permits serial communications between the servo amplifier
and a PC. Using the Windows-supported setup software, functions such as parameter setting,
test runs, status display, amplifier setting, etc. can be carried out. By means of real-time auto­tuning it is possible to undertake an automatic adjustment of the amplifier settings to the
machine.

The MR-J2-Super series servo motor is equipped with an absolute position encoder which has
the resolution of 131072 pulses/rev to ensure more accurate control as compared to the MR-J2
series.

Simply adding a battery to the servo amplifier makes up an absolute position detection system.
This makes home position return unnecessary at power-on or alarm occurrence by setting a
home position once.

1.4 Removal and reinstallation of the front cover

For models MR-J2S-200B or larger the front cover must be removed before the battery holder
and terminal strips for connecting the power supply of the motor TE1) and control voltage (TE2)
are accessible.

DANGER:

Prior to removing the front cover the power supply must be switched off and at least

m

10 minutes must then elapse. This time interval is required for the condensers to
discharge to a harmless voltage level after turning off the mains power supply.
